Specification of Letters Patent.

Application filed November 9, 1911. Serial No. 659,271.

Be'it known that I, RICHARD "W. BooAR'r, Jr., a citizen of the United States, and resident of the borough of Manhattan, city," county, and State of New York, have nvented certain new and useful Improvements in Sanitary Shields for Telephone- Transmitters, of which the following is a specification. v

This device is intended to be more or less permanently attached to a telephonein such a manner that a user of the telephone may,

with little or no difficulty place over the .mouth-piece a clean sheet of paper or shield,

and I have so arranged my device that a continual supply of fresh paper will be always'adjacent to and in operable relation with the receiver.

This device, although primarily intended for use in public pay stations, or in connection with other telephones arranged for common service, may be found of great advantage as an adjunct to any and all instruments of a like nature. I will describe my device as used in connection with an ordinary telephone, but I know of no reason why it cannot be successfully used in con junction with a 'dictaphone or any other voice receiving apparatus.

The following is what I consider the best means of carrying out this invention.

The. accompanying drawings form a part of this specificatiorn'in which Figure 1 is in side elevation, it shows an ordinary telephone transmitter to which has been secured my device. Fig. 2 is a plan view corresponding to Fig. 1, but in this view the paper is omitted, as is the mouthpiece. Fig. 3 shows in plan a sheet from which the metallic parts of my device may be folded.

Similarreference numerals indicate like parts in all the figures where they appear.

In my experiments I have secured my device to an ordinary transmitter of an ordinary desk telephone instrument and I will therefor describe so much of the telephone as I find necessary.

At 1, I have shown the base or cup of the telephone receiver, and at 2 the clamp by which the cup is secured to the upright. The flanged disk 3 closes the upper side of the cup and is provided with a central perforation 4, into which is screw-threaded a flared mouth-piece 5, which may be of fiber,

rial. tom of the cup member 1, admits the cable 6. -So far I have described the exterior of an ordinary telephone transmitter.

A plate 7, which may be sheet or block tin, and which is oblong in plan, though.

provided with numerous projections is also provided with a central perforation 8, which is intended to register with the perforation 4, of the plate 3. A hinge 9 is formed in oneend, the upperend of the plate 7, and into this hinge I have connected a cap' or closing plate 10. Formed integral with the plate 7 and at the ends of the hinge-9 are the partially circular projections 11, and-l2, which are intended to bend upwardly and at right angles to the plane of the plate 7. The closingcap 10 is bent to fit closely to the periphery of the circular part of the plates 11 and 12, and an additional closing part or cap 13, which may be secured to the plate 7 by soldering and which is correspondingly bent, is arranged to connect the front or lower sides of the plates 11 and 12, forming with a portion of the base 7, the hingedly connected cap 10, and the plates 11 and 12 a semi-cylindrical chamber the purpose of which shall appear later. It is my intention that the caps 10 and 13 shall not extendlcompletely about the outside ed e of the plates 11 and'12, but that they shall re-. main 9. "distance apart at the top so as to produce a slit or opening 14.

Each ofthe plates 11 and 12 are provided with radial slots 15 and 16 respectively, and

An insulated perforation in the bot- STATES PATENT OFFICE.

I have shown a bar or shaft 17 which should be round and .headed on each end and which should be'provided with a longitudinal slot 18. Upon this-bar 17' I intend to wind a quantity of strong though thin tissue paper.

to produce the roll 19. The width of the paper must not be greater than the width of the plate 7, and the roll or bar 17 must be of suflicient length to project from the outside edges of the plates 11 and 12.

The bar 17, bearing the paper ed into the slots 15 and 16 and when the cap 10 is closed the projections 20 and 21 secure the roller rotatably in the forward end of the slots 15 and 16. To the exterior of the plate 11 I have secured a lock of simple construction and formed integral with the projection 21 is a hook which passes into the lock and is secured there by means of the bolt of the look a.

The free end of the paper from the roll 19 is insert- I 19 is passed through the slot 14 and over the ing standards which may be formed integral with the plate 7. These rollers 22, 23 may be metallic shafts provided with rubber surfaces or they may be metallic shafts upon which wooden cylinders have been secured,

and if the latter are used I prefer that sand or emery, or some other like material shall be applied to the face of either of both rollers. Oneof the rollers should be provided with means for rotatingit by hand and for that purpose I have secured tothe shaft of the upper roller-22, a knurled button 22*, and I have also secured to this shaft a ratchet 24 operable with a simple spring pawl 25, whichprevents the roller'fro-In being turned backward.

Adjacent to and immediately below the rollers 22, 23 I have provided a slit 26, which is saw-cut or roughenedon each edge and I propose that the paper shall pass through this slit after leaving the rollers 22, 23. This'roughened slit is produced in a plate 27 which may besupported by and formed integral with thebase plate 7.

In operation it ma be found desirable to lock this device to t e transmitter and for 7 that purpose I have provided a member,

also supplied with a perforation, adapted to register with the perforation 8 of the plate 7.. Two outstanding arms from this member indicated at 28 and 29 are adapted to be folded back over the body 1 of thetransmitter, and a series of short ri ht-angled pro ections 30 and 31, each 0 whichis provided with a perforation, comprise the securing means for the clamp. I may bolt the clamping means upon the receiver or I may use one bolt and one look, or two locks as occasion may require.

The operation of this whole structure is not difiicult to understand, it is as follows 'lhe lock A being opened allows the cap 10 to be folded back to admit a roll of paper 19,

. the cap 10 is then closed forcing the paper .to assume a central position in the semicylindrical chamber, and the free end of the paper to pass upward through the slot 14;. The end of the paper is then carried across the exposed open top of the transmitter mouth-piece and inserted between'the two rolls 22 and 23, it isnow ready for use and after being used, or before the next use the button 22 is turned causing the paper to traverse the mouth-piece and project through the slot 26. After a suflicient quantity has been thus caused to unroll from the roll' 19, an upward or downward'motion of the free end will cause the saw-teeth to cut the paper, releasing the free projecting end of the paper.

It is my intention to provide a series of marks upon the upper-exposed surface of the paper. which will indicate when the paper has reached the proper position to present a clean and fresh surface, over the mouth-piece of the transmitter.

Modifications may be made within the scope of the appended claims without departing from the principle or sacrificing the advantages of this invention. The clamping means for securing the device to the transmitter may be omitted, and. changes in the construction may be made by a good meit is obvious that it may be secured to either roller with equal efiiciency.

Having carefully and fully described my invention, what I claim and desire to secure by Letters Patent is 1. In a device of the character described, a semi-cylindrical member, means for sup porting said member, asevering member and means for supporting it, and, a plurality of rollers arranged adjacent to said severing member and provided with means for rotating them for passing a shield from said semi-cylindrical member to said severing member as herein specified.

2. In a device of the character described, a plate, a semi-cylindrical chamber hingedly secured to said plate, a paper roll held in said chamber, a plurality of rollers and means for operating them, means formed integral with said plate for supportingsaid rollers, and means formed integral with said supporting means for severing. the paper after its passage through said rollers, in combination with means for securing the whole tothe body of the transmitter of a telephone as herein s ecified,

Signed at New ork city, in the county of New York and State of New York this 2nd day of November 1911.
